Name: Larrea tridentata - Encelia farinosa Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: This widespread alliance occurs in the Mojave, Sonoran and Colorado deserts and extends into the southeastern Great Basin. Stands occur on alluvial fans, bajadas, upland slopes and minor washes. Sites are gentle to moderately sloping. Substrates are typically well-drained, rocky soils derived from colluvium or alluvium, and/or with a pavement surface. The vegetation is characterized by an open, xeromorphic shrub layer codominated by Larrea tridentata and Encelia farinosa. Cover of either species does not exceed the other by more than twice, and no other species greatly exceeds the cover of both combined. Other desert shrubs and dwarf-shrubs may be present to codominant including Agave deserti, Ambrosia dumosa, Bebbia juncea, Fagonia laevis, Ferocactus cylindraceus, Krameria grayi, Opuntia basilaris, Opuntia bigelovii, Peucephyllum schottii, and occasional emergent Fouquieria splendens. The herbaceous layer is typically sparse with scattered Dasyochloa pulchella (= Erioneuron pulchellum), Pleurocoronis pluriseta, or Stephanomeria pauciflora. Abundant annuals such as Eriogonum inflatum may be seasonally abundant.
